AS ONE watches the high-speed chase scenes in the new “Deadpool 2,” in which the character Domino (played by Zazie Beetz) relies on her super-powered luck to navigate the violent mayhem all around her, the memory of Sequana “S.J.” Harris looms over the action.

Ryan Reynolds, the film’s title star, posted a statement on Twitter at the time that said: “We’re heartbroken, devastated … but recognize nothing can come close to the grief and inexplicable pain her family and loved ones must feel in this moment.”

And director David Leitch said in August, “No words can express how I and the rest of the Deadpool 2 crew feel about this tragedy.”

Josh Brolin, who plays Cable in the film, told the Associated Press in October that the “freak” street accident in Vancouver’s Jack Poole Plaza “wasn’t even a stunt.” He called Harris “a wonderful woman.”

“Deadpool 2” was the only film that Harris worked on as a stunt performer.

She is remembered by many for a race career that began in 2013, when she became the first African American woman to be licensed for American Motorcyclist Association competition. Her first Championship Cup Series race was in 2014.

She told Black Girls Ride in 2015: “I am everything people never saw in this sport. Sisters on the track are few and far between. I want to show them that there’s more for them to be exposed to.”

When Harris died, Beetz called the road racer “one of our own.”

The film’s dedication to Harris stands as an expression of that sentiment.

Correction: An earlier version of this post referred to Josh Brolin as John Brolin.
